GI 275 Issues Entering Config Mode

[mooneypilotlq]

Hi all 

 

Having issues going into config mode on my GI275s, need to do so in order to complete the yearly capacity test.

 

I followed the instructions and get to the that counts down before entering config mode , and then it just reboots, any thoughts or ideas will be appreciated

I'm coming up on a year since installation of two GI275s.  Battery test is required yearly for IFR, but the pilot guide says 392 days.  Pilot guide just says it needs to be done but not how.  Pilot guide says refer to the Installation Manual that Garmin doesn't hand out.  AFMS is no help either.  Does this mean the radio shop must be visited?  Sigh.

Don't know where I got this part of the install manual.  Is this what you are doing now?

5.12.5 Backup Battery Check This procedure will analyze the voltage and discharge qualities of the installed backup battery. The procedure is required to be completed on initial installation and every 12 calendar months when a backup battery is installed in the system. A fault indication message will be displayed in Normal mode until this procedure is completed. NOTE The battery rundown test may take up to 150 minutes to complete. NOTE The battery rundown test date is reported in UTC. To complete the backup battery test, complete the following steps: 1. Power on each GI 275 with an installed backup battery in Configuration mode. 2. Navigate to the Backup Battery Test page (Calibration/Test → Backup Battery Test). 3. Touch the Before Test Checklist button. 4. Verify that “Discharging” is not displayed under Battery State. 5. Touch the Test Date button and enter the current date. 6. Complete the on-screen checklist. Touch each checklist item once completed. Once all checklist items have a green check mark, touch the Back button. 7. Touch the Start Test button and follow the on-screen commands. 8. The GI 275 will power off automatically when the test is completed. 9. Power on the GI 275(s) in Configuration mode and navigate to the Backup Battery Test page. 190-02246-11 GI 275 Part 23 AML STC Maintenance Manual Rev. 1 Page 5-35 10. Touch the Test Results button and then Rundown Test Results button. a. The results are displayed the date the test was performed and how many minutes until the battery ran down. 11. For aircraft that are approved for flight over 25,000 feet, a rundown time of at least 60 minutes is required to be considered a PASS. For aircraft that are only approved for flight at 25,000 feet or less, a rundown time of at least 30 minutes is required to be considered a PASS. 12. If the test results were not a PASS as described in the previous step, the battery must be replaced using the procedure in Section 5.5.

Did you touch Accept?

The Maintenance Manual contains Instructions for Continued Airworthiness -- that has the information you are looking for. The installer should have provided that with your documentation.

I’d try releasing the knob when the countdown screen first appears. If that doesn’t work, then I’d take it back to the dealer.
